PACKER. FOR STOCK FEED.

; Specification of Letters Patent.

Patented Mar. 11, 1919.

Application filed April 19, 1918. Serial No. 229,585.

for Stock Feed; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

The present invention relates to improve ments in packers,-and has foran object to provide an improved packer especially adaptable for packingstock feed in sacks. v

Another object of the present invention is to provide an improved packerof simple construction adapted to operate quickly and efliciently, andwherein the feed or other material to be packed may be readily loadedinto the machine, and the empty bags quickly put in place and afterbeing filled quickly removed.

In the accompanying drawings forming a part of this application, and inwhich similar reference symbols indicate corresponding parts in theseveral views: I

Figure 1 is an end elevational View, with parts shown in section of animproved packer constructed in accordance with the present invention.

Fig. 2 is a longitudinal vertical sectional view through the improvedpacker taken at right angles to Fig. 1, and showing in dotted lines theadvanced position of theplunger.

Fig. 3 is a top plan view of the improved hopper.

Fig. 4 is a horizontal sectional view taken on the line H in Fig. '1.

gig. 5 is a plan view of the guide plate; an

Fig. 6 is a crosssectional view taken on the line 6-6 in Fig. 2.

Referring more particularly to the drawings, 1 designates a plunger ofsubstantially elliptical form as shown in Fig. '6, fitted to movethrough an elliptical casing 2 having a delivery mouth 3 about which isarranged a double series of staggered pins 4 for receivin the mouth of asack or other receptac e 5.

The side walls of the casing 2 are extended to form a hopper 6 havin theinclined bottom 7 which directs the fee or other material deliveredthereto into the casing 2;

there is a cut-away portion 8 provided at the upper end of this hopper 6in order to enable the operator to look in beneath the plunger 1 andascertain the amount and height of the material in the casing 2, and tootherwise inspect the interior of the hopper and casing. The casing 2and hopper 6 are supported in any suitable manner, preferably by braces9 and 10, which are shown in Fig. '1 to diverge upwardly and be boltedor otherwise fastened to appropriate supports.

A piston rod 11 driven b a piston which reciprocates in a cylinder 12disposed above the casing 2, is'threa'ded through a central and threadedopening in the plunger 1 and locked therein by a lock nut 13. The pistonin the cylinder 12 is preferably composed of three steel disks l4:spaced apart by cupped leather washers 15, the ends of which bearagainst the cylinder walls. These disks 14 and washers 15 are, as shownin Fig. 2, fitted over the reduced end 16 of the piston rod 11 and heldthereon by a nut 17. At its upper end the cylinder 12 is closed by ahead 18 having a cylindrical flange 19 threaded to engage the threadedupper end of the cylinder 12. Brackets 20 are provided on the cylinderhead 18 and cylindrical flange 19, and are adapted toreceive bolts orother fastening means 21 by which the upper end of the cylinder may beheld on a support.

In like manner the lower end of the cylinder 12 is closed by a head 22formed with the cylindrical flange 23 threaded on the lower end of thecylinder. This lower head carries a guide plate 25 'having openings 26in any suitable number therein, and carrying thereon a bracket 27 whichenables the lower end of the cylinder to be fastened to some object. Thelower head 22 also carries a stufling box 28 containingpacking bag 29surrounding the piston rod 11 and held in place by the gland 30. Theheads of bolts 31 engage this gland 30 whereby to hold same in place,such bolts or screws being attached or threaded into the cylinder head22. 7

Guide rods 32 provided in suitable number, corresponding to the numberof the openings 26 in the plate 25, are slidingly fitted through saidopenings 26 and are attached to and movable with the plunger 1. For thispurpose the plunger is preferably provided With small threaded openingsto receive the lower threaded ends 33 of such guide rods 32. The purposeof the guide rod-s is to steady the plunger 1 as it moves through thecasing 2.

A compressed air pipe 34 from a. suitable source of supply, is providedwith the branches 35 and 36 leading respectively to the upper and lowerends of the cylinder, each of such. branches including shut-01f cocks 37and 38. A threeway or other valve 39 having operating means actuated byhand or automatically, is provided to turn the compressed airalternately into the up- 'per and lower ends of the cylinder 12 so as toreciprocate the piston.

The operation of the. invention is substantially as follows:

With the plunger 1 in the raised position shown in full lines in Fig. 2,the feed or other material to be packed is dumped into the open upperend of the hopper 6 and is diverted by the inclined wall 7 into thecasing 2 below such plunger. This material passes freely through thedelivery mouth 3 of the casing 2- and into the receptacle 5, which hasbeen previously aflixed to the hooks or pins 4 in the manner shown. T heoperator may constantly observe the height of this material, and whensame rises to an appropriate level the deliver I of further material maybe cut off to prevent overflow of the hopper and casing.

The valve 39 is now moved to direct C0111- pressed air through thebranch pipe 35 into the upper end of the cylinder 12, the cocks 37 and38 being normally open. This introduction of compressed air will drivethe piston down, causing the plunger 1 to be also driven downwardlythrough the casing 2,

pushing before it the material, which it packs into the bag orreceptacle 5.

The plunger 1 may be driven to any lowered position required. Generallyit will be found desirable 'to drive it to substantially the positionshown in dotted lines in Fig. 2, which will allow sufficient space abovefor the bringing of the mouth. of the bag together for tying. lVhen thebag is thus filled the valve 39 is turned to the position where it willallow the compressed air to pass through the branch 36, at the same timeclosing the branch 35, and compressed air will therefore be put intocommunication with the lower part of the cylinder 12, where it willbecome efiective to raise the piston and return the plunger 1 to theinitial position at the top of the casing 2. The sack 5 is now removedfro-m the pins 4 and an empty sack substituted, whereupon the abovedescribed operations are repeated.

I claim:

In an apparatus having a casing, means whereby a receptacle to be filledmay be supported with its mouth beneath the easing, and means travelingthrough the casing for driving material therein into the receptacle, thecombination of a hopper formed by extending the side walls of saidcasing, the hop er bottom being inclined whereby to direct the materialinto the casing and through the delivery end of the latter, said hopperhaving a portion thereof cut away to enable the operator to look beneathsaid material driving means when the latter is in a retracted position,substantially as de scribed.

in testimony whereof, I affiX my signature.
